STATS JAMES A. DUCKETT, OF COLUMBUS, OHIO.

VENDIN Gr MACHINE.

Application filed February 1, 1922.

To (rf/ wim/lt t may concern.

.lie it' known that .latins A. Dnoign'r'r, citizen ot' the United States, residing at Columbus, in the county of Franklin and State olf Ohio, has invented certain new and uselul improvements in Vending Machines, ot' which the following is a spec-iiication.

rl`his 'invention relates to vending machines and has special reference to a vending machin-e ifor dispensing hot edibles such as peanuts, pop.orn and the like.

lr-'lorc particularly the invention relates to an inil'novement on the peanut vending machine lior which application for Letters Patent otl the United States wasI made on Aul application bearing the Serial Number 196,198 and being made by James A, Duckett and Joe H. Leslie.

in the apparatus 'forming the subject matter ot the aforesaid prior application the contents oli' the peanut holder were arranged to be heated by an ordinary incandescent lamp suspended centrally oi the mass of peanuts. It. has been found by experience that, under these conditions ot' heating, the peanuts adjacent the delivery opening or gate were inetfectually heated and whenever the machine stood for some time without being used the first peanuts delivered were practically cold.

The principal object of the present invention is to provide an improvement ot' the device ot the aioresaid application wherein the peanuts are heated in such manner| that they are always hot when delivered.

A second important object of the present invention is to provide an improved attachment 'for peanut vending machines which is arranged to heat the peanuts immediately adjacent the delivery opening or gate of the machine.

A third important object oitl this invention is to provide an improved attachmenttor peanut vending machines ot' the type in which the peanuts ai'e sto-red in a glass globe` the attachment being of such charac ter that it. may be Yinterposed between the la'lol'ie and base and when in operation effectually heat the peanuts ready vfor delivery.

lV ith the above and other objects in view, the invention consists in general of certain novel details of construction and combinations oif parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

Serial No.' 538,258.

In the accompanying d awings, like characters of reference indicate like parts in several views, and

Figure l is a side elevation ot' the vending machine with the improved heating arrangement in place.

Figure 2 is a vertical section through certain parts of the device showing the heating attachment.

.Figure 3 is a plan view of the globe cap or ring used herewith.

Fig. 4 is a detail section through a portion of the heating attachment showing the heat.- ing element in position, the view illustrating the channel structure adjacent the delivery opening of the device.

Fig. 5 is a detail view similar to Fig. 1f, but showing the slight n'iodiiication ot' the manner of supplying electric current to the heating end, both Figures l and 5 being taken substantially on the line l-a and 5 5 respectively of Fig, 2.

In the embodiment` ot the invention herein illustrated the general construction is similar to that oiu `the application above nientioned and like that iorm of the device the construction embodies a hase 1() wherein' is located the coin controlled apparatus which serves to lock and release the usual valve le ver 11 controlling the flow of peanuts through the gate 12.

The reservoir body of the device consists of a hollow glass globe 13 on top ot' which rests a ring ll having a cross bar 15 extending diametrically olE the ring. Through this cross bar extends a pair of bolts 16 which serve in the usual manner to secure the globe on the base. A cap i7 is provided which acts as a closure for the top ot the globe, being removable 'for the purpose oi filling the apparatus and being provided with a suitable locking device to prevent tampering with the contents of the globe by unauthorized persons. These parts are. in their general t'eatures, old and well known and, as the present invention does not reside in any specific features of these parte, it is not dee-med necessary to describe and illustrate the exact details of construction of such parts. @n top ol' the cap 17 may be arranged an electric lamp 18 as shown in the prior application.

he improvement itself consists in interposing between the base and the globe a heating device which consists ot ring 1,9 of

ill

inverted channel shape and within the inner periphery of this ring is a floor or bottom 2O on which the conte-nts of the globe rests. rThis bot-toni is inclined4 downward toward the portion of the ring, adjacent the Lrate and is there provided with an opening 21. Around the outer periphery of the ring eX- tends a bead 22 and wit-hin the space bounded by this bead rests the bottom of the globe 13. 'lhe ring itself rests on the base so that. the device is thus interposed between the globe and base and forms a bottoni for the former.

The opening 2l communicates by the usual valve controlled passage (not shown) with the delivery rate l2. Within the channel of the ring,- is fitted a heating element 23 of the usual spirally wound form and the lead wires 24 from this element may either run up through a tube 25 to the cap 17 and be there connected to the lamp and line wires 26 or may run laterally out of the channel as shown in Figure 5. An asbestos lining 27 is preferably used in the channel to keep the outside from getting,` too hot and the heating element is preferably held in place by set screws 2S.

ln operation it will be seen that the peanuts on the false bottom will receive the greater amount of heat and that the greatest heat will be received by those peanuts lying against the ring at the opening- 21. Thus the peanuts ready for delivery will always be thel hottest.

There has thus been provided a simple and efficient device of the kind described and for the purposes specified.

lt is obvious that minor changes may be ma de in the form and construction of the invention without departing?,` from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is 2- 1. In a vending,` machine, a reservoir for articles to be dispensed. a delivery mechanism connected therewith, and a heating device arrang'ed around the periphery of the reservoir bottom which heats said periphery only and located adjacent the path of the articles from the reservoir to the delivery mechanism.

2. In a vendingimachine, a reservoir for articles to be dispensed, said reservoir having a bottom provided with a delivery opening, a delivery mechanism beneath the reservoir and communicating therewith through said opening, and a heat generating` device interposed between the reservoir and delivery mechanism and arranged beneath the periphery of the reservoir bottom to heat the articles in the reservoir and as they pass from the reservoir to the delivery mechanism.

3. ln a vending, machine, a reservoir body for articles to be dispensed, a delivery mechanism beneath the reservoir body, a heating device interposed between the reservoir body and delivery device, the reservoir body having a delivery opening* in its bottom adapted to feed into the delivery' device, said heating device beine,` arranged beneath the periphery of the bottom.

et. ifi heating` attachment for a machine for vending' peanuts and the like including a ring;` memberl of inverted cup shape, said ringv member having,` a bottom provided with horizontally disposed peripheral portion, the bottom extending' vertically downward from one part of the peripheral portion and beine` inclined down from the opposite part, there being);- an eccentrically disposed opening in the bot-tom at the lower ends of the inclined and vert-ical portions, and an electrical heatingv element supported in the cup beneath the horizontal portion of the bottom.

5. A heating attachment for machines for vending` peanuts and the like including a ring member of inverted cup shape provided with a bottom having an eccentrically disposed opening, said bottom sloping downward toward the opening, and an electric heatinp,- element mounted in said channel ring.

G. A heating attachment for machines for vending peanuts and the like including a ri ng member of inverted channel shape provided with a centrally disposed bottom having an opening at one portion adjacent the ring', that portion of said bottom at the side of the opening,r remote from such periphery sloping' downward toward the opening and at the other side slopingT vertically, and an electric heating element mounted in the channel thus formed around the'openino.

In testimony whereof I aflix my signature.

JAMES A. DUCKETT.
